Optoelectronic elements are all devices working in the field of optical radiation. These are LEDs, light detectors, lasers, optical fibers and displays. The basis for the operation of these elements is the interaction of photons and electrons. In terms of functionality, optoelectronic components can be divided into semiconductor light sources, semiconductor detectors and radiation converters. Optoelectronic elements help in the operation of devices and make their use and appearance more attractive.
